This is an introductory geochemistry course for scientists and engineers working in the field of groundwater site characterization, contamination, and remediation.
It is designed to provide basic information on geochemistry that is necessary to understand natural and contaminated systems and how the composition of groundwater evolves along its flowpath in the subsurface.
Geochemical processes that will be described and discussed include solution complexation reactions, solution/gas interactions, mineral dissolution/precipitation, oxidation/reduction, and adsorption/desorption. Data collection, presentation, and interpretation of results will be discussed.
Examples that illustrate the concepts are described throughout the class. At the end of this one-day class, attendees will have a better understanding of the types of geochemical processes that affect groundwater composition, the importance of collecting sufficient data to understand site-specific geochemical systems, and how to use data to evaluate contaminant occurrence and mobility in the subsurface.
This course is being held in Perth and Brisbane to supplement the Introduction to Organic Groundwater Geochemistry Course.
Perth – 17th November 15 – 9am – 4pm
Brisbane – 25th November 15 9am – 4pm

Hydrogeology in Mining: a one day conference to be held in Adelaide SA, 1 May 2015.
Following the success of AIG South Australia Branch’s inaugural hydrogeology conference in 2014, the organisers invite proposals for presentations (call for papers) about hydrogeology in mining: exploration, geophysics, water supply, dewatering, impact assessment, monitoring, compliance, closure etc; or an overview of a particular issue related to the hydrogeology in mining.
If interested in presenting, please send a page abstract to firstname.lastname@example.org by Friday, the 27th February 2015.
AIG’s South Australia Branch hydrogeology group will be holding their inaugural meeting on Wednesday 1st October at the Wakefield Hotel, Adelaide. The speaker will be Tavis Kleinig (Water Quality Branch of the EPA, Senior Hydrogeologist) and his talk topic is ‘The EPA and Groundwater – From AMD to UCG’.
The success of the recent South Australia Branch “Groundwater in Mining” conference demonstrated the need for a hydrogeology group, particularly in South Australia.
“Tavis Kleinig’s talk is a must for exploration and mining geologists in South Australia, for obvious reasons” according to AIG South Australia Branch Chairman Graham Teale. “His talk will focus on the Environment Protection Authority’s (EPA’s) broad role in the assessment of groundwater, and the assessment of mining and oil and gas projects with potential to impact groundwater.”
Tavis will provide a summary of a recent project, the State Groundwater Quality Monitoring, Evaluation and Reporting Program (SGWQMERP for short!). To keep things topical (and hopefully more interesting) Tavis will briefly discuss the EPA’s role in the recent Clovelly Park investigation, Rex Hillside, Unconventional Gas (UCG) in the South East, and finally introduce everyone to stygofauna!

The CSIRO Mineral Resources Flagship will hold two mining and exploration seminars in Mount Isa, Qld and Perth WA during November.
The first seminar on Monday the 10th November 2014 at the Ibis Styles in Mount Isa will examine the latest research into exploration concepts and tools being developed by the Mineral Resources Flagship in CSIRO. Presentations will focus on research in the Mount Isa Inlier or applications that could be used in Mount Isa. The diverse series of presentations are listed below. Additionally, the final session will be an open panel discussion to better understand exploration challenges in the Mount Isa Inlier and potential solutions through research.
- Mineral systems approach to exploration
- Hyperspectral data and the Mount Isa Inlier
- Regolith processes and the Mount Isa Inlier
- Geophysical case studies of the Mount Isa InlierGesocience data and seemless access for industry
- Probabilistic modelling – Mine case study
- Alternative views on the tectonics of the Mount Isa Inlier
- pXRF best practice and applications
- Landscape evolution modelling for mineral exploration
- Stable isotopes in mineral exploration
- Advanced characterisation facilities
The Perth seminar will be held on Thursday the 13th November 2014 at the Australian Resources Research Centre in Perth. The seminar provides the latest research into exploration concepts and tools being developed by the Mineral Resources Flagship in CSIRO. Presentations will be targeted at Australian exploration issues, ranging from the application of ultrafine fraction gold for exploration in regolith dominated terrains to magnetic remnance and magma physics of sulfide systems.
- Stable isotopes and mineral exploration
- Advancing exploration using spectral data
- Calcrete and plants and their link to gold mineralisation
- Landscape evolution and exploration in the Albany-Fraser Orogen
- Isotopic terrain mapping
- Indicator heavy minerals for exploration through cover
- Uranium mineral systems
- Groundwater isotopes and ratios for exploration in the Northern Yilgarn Craton
- Advanced characterisation: new insights into exploration and resource samples
AIG members are entitled to discount registration for both seminars.
Brisbane geoscientist, Helen Coles, was recently announced as a runner-up in the Queensland Government’s Science for Solutions open data competition.
Helen works with Rio Tinto Exploration in Brisbane, specialising in GIS analysis of exploration data.
Her award was for a smartphone app design that provides farmers and other rural landusers with access to groundwater data compiled by government agencies by mapping water bores and displaying the available data for them. This information is of real benefit to landholders, particularly in areas where coal seam gas development is occurring and management of water resources is critical to ensure existing landuse is not adversely affected by gas extraction. Helen’s app provides a visual representation of actual and proposed Coal Seam Gas (CSG) well depth in relation to water tables. It is designed to: increase stakeholders’ understanding of the interaction of wells with the water table; assist with infrastructure design and assessment; and reduce potential conflicts between different stakeholder groups.
The Science for Solutions open data competition awards were presented on Friday 11 July 2014 at The Cube, Science and Engineering Centre, Queensland University of Technology, as part of the GovHack-Brisbane event launch. The purpose of the competition was to promote the use, reuse and re-purposing of science data freely available on the Queensland Government open data portal. This initiative also encouraged the creation of data visualisations, application development and other unique treatments of the science datasets provided by the Department of Science, Information Technology, Innovation and the Arts.
The competition represents an innovative way of promoting effective use of public geoscience data by government. There are two sections to the competition: one for schools and an open competition. Other entries to receive awards included:
- a website and app designed to provide clear and relevant scientific information about the many species of animals from inland, marine, coastal and waterway areas as well as prehistoric information throughout Queensland;
- a mapping and reporting application designed to assist agencies rapidly assess the risks and impact of natural disasters on agriculture and horticultural areas;
- a web-browser based application that allows users to intuitively visualise, overlay, combine, filter and perform statistical analysis on data. Users can easily access other online data sources such as Queensland Government Open Data to complement other data;
- applications to assess bushfire risk, and deliver re- or near-real time information to landholders and residents affected by bushfire emergencies;
- a data visualisation, using the Queensland Globe, designed to help resolve the competing ground water uses (uptake and discharge) by different stakeholders (e.g. mining companies, farmers, government) and consider the impacts on natural systems such as groundwater dependent ecosystems; and,
- a mobile app and visualisation tool enabling farmers to identify groundwater wells susceptible to salt table rising, and modify their management strategies to maintain farm productivity.
Congratulations to all those recognised for their entries and to the competition organisers for their contribution to promoting effective, transparent and innovative access to and use of public geoscience data.
